Patented May 29, 1934 omrso s'mrss PATENT QFFEE Claims.

This invention relates to pipes and to fittings adapted to be employed in connection therewith.

It is an object of the invention to provide a pipe in which the tendency for the passageway from bowl to the stem to become clogged is greatly lessened.

It is a further object of the invention to provide means for readily clearing such passageway should the same become temporarily obstructed.

Another object of the invention is that of furnishing a fitting for use with a pipe which acts as a scraper for the side walls of the pipe bowl and thus serves to keep the pipe sweet and clean.

With these and other objects in mind, reference is had to the attached sheet of drawings illustrating practical embodiments of the invention and in which:

Fig. 1 is a partly sectional side elevation of a pipe, showing one form of the invention;

Fig. 2 is a sectional side elevation of another form of the invention;

Fig. 3 is a sectional side elevation of a still further form of the invention;

Fig. 4 is a sectional plan view taken along the lines 1-4 of Fig. 3;

Fig. 5 is a partly broken away side elevation of a further form of the invention; and

Fig. 6 is a plan view of the device shown in Fig. 5 in position in the bowl of a pipe.

A pipe 35 or" any well known shape having a stem 36 is provided with a bore '7 which leads from the stem to the pipe bowl 8. While this bowl might take any of the several shapes now commonly in use, it is preferred in this embodiment that it be substantially cylindrical in contour and be formed with shoulders 3'7 at the top and bottom of the bowl.

The top of the bowl opening may be tapered as at 9 for a reason which will be brought out later. Cooperating with the bowl and in registry with the top thereof is a ring 10 which may be formed of bakelite, wood, or other durable ma terial, preferably of a heat-resisting and nonconductive nature. Secured to this ring is an inner band 11 which is held in place by means of rivets 12 or the like. This band has a series of depending supports 13 extending to a point adjacent the bottom of the bowl opening. At this point they are secured to another band 14 formed with a plurality of openings 15 around its entire circumference. These openings are of an area substantially the same as that of the bore 7 and are so positioned as to be progressively in registry therewith.

It will be noted that the diameter 01' the bands 11 and 14 is substantially that of the bowl taken at the shoulder portions 37 so that the bottom band and the upright supports keep the device in snug position with respect to the bowl. It is possible, by simply turning the ring 10 and its dependent structure, to present any oneof the apertures 15 to the bore 7 and in complete registry with the latter. It will be observed that the supports 13 act as scraping mem-- bers when the device rotated with respect to the bowl opening, but due to the fact that there is a space 38 between the inner wall of the bowl and the supports, room is left for the so-called caking of the pipe to occur. At the same time, any excess tobacco, which would merely serve to fill the bowl opening is removed and thus the capacity of pipe remains constant. For those who object to the formation of a cake inside of the bowl, it would be possible by eliminating the shoulders 3'7, and increasing the diameter of the bands, to scrape the bowl clean of tobacco after each smoke.

In 2 is shown a similar bowl-engaging ring 16 formed with an inner band 17 which may be secured by the conventional rivets 18 or in any other suitable manner. Supports l9 depend therefrom and secured to these supports is a band 20 formed or" a series of opposed arcs which are joined together to present a wave-like appearance to the hand. It is apparent that with such a device in place in the bowl shown in Fig. 1 by simply turning the ring 16 it would be a simple matter to present an opening from the bowl to the bore of the pipe.

In Fig. 3 a ring 21 has secured to it an inner band 22 fastened by means of rivets 23, or in any other desirable way. Depending supports carry a band 25 which has triangular shaped openings which are alternately positioned to stand on the base and apex respectively. This device would function in a. manner similar to the two already described.

Referring now to Fig. i, it will be seen that the supporting members 24 are three in number, but quite obviously more or fewer of these supports might be substituted without in the least departing from the spirit of the invention. It will be noted that the outer edges of these supports as at 26 define sharp, clear cut angles so as to have a better scraping effect on the side walls of the bowl. By accentuating these edges 26 and tapering off the side walls of the support, this scraping effect could, of course, be improved.

The device shown in Fig. 5 has a ring 27 carrying supporting arms 28 and a bottom band 29. It will be noted that the ring in this instance has a shoulder 2'7 which may be substituted for the upper shoulder 37 of the pipe bowl. The band is divided in this instance into three segments, the boundaries of which are defined by the points of juncture of the supporting arms 28. In the form shown, each of these segments is provided with a plurality of different sized openings, the

openings of one segment being fine, the next, medium and the last, large.

As shown in Fig. 6, the ring has been notched at 30 to show the boundaries of the respective segments and is further provided with indicia 31 to indicate the size of the openings in each particular segment. The pipe bowl is provided with a keying mark 32 so that the user can tell when he has the openings of a particular segment in line with the stem opening of the bowl. This form of band is adapted for use with fine cut as well as long cut tobacco, and by using the small openings with the former and the large openings with the latter, a steady draft is assured at all times without the danger of clogging. It is, of course, apparent that a band might be formed with a continuous succession of openings of any desired size in much the same manner as is done in one segment of this particular adaptation.

In operation the smoker inserts the device in the bowl of the pipe and thereafter fills the latter with tobacco and proceeds to smoke. Should the stem bore become obstructed by particles of tobacco or tar deposits, by simply twisting the top ring he is able to clear the obstrutcion away from the bore and present a new opening from the bowl to the same. After concluding his smoke, another twist of the ring will serve to loosen the ashes in the bowl and facilitate their removal and at the same time the side walls of the bowl will be scraped free of any deposits or accumulation which may have adhered thereto. In this manner it is always possible to keep a pipe free and sweet and to prevent the same from caking in an undesirable manner. In order to facilitate complete removal of the attachment the top of the bowl is slightly tapered as aforementioned so that after the attachment has been cleaned, it may be once more readily inserted within the bowl. If desired, indicia might be placed on the outside of the bowl and on the ring so that by placing corresponding inclicia in registry the user would know just when the opening in the bottom band was in registry with the bore of the pipe.

From the foregoing it will be apparent that among others the several objects of the invention as aforenoted are achieved. Obviously, numerous other changes and rearrangements of the parts may be resorted to without departing from the spirit of the invention as defined in the claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A device for association with the bowl of a pipe comprising a serpentine band for cooperation with the inner wall of said bowl adjacent the stem opening of the latter, supports extending upwardly from said band and an operating ring carried by said supports for rotating said device.

2. An attachment for the bowl of a pipe comprising a serpentine band for cooperation with the inner wall of said bowl adjacent the stem opening of the same, scraping arms extending upwardly from said band and in registry with said inner bowl wall and an operating ring carried by said arms for rotation of said arms and band with respect to said bowl.

3. A pipe including, in combination, a stem formed with a central bore, a bowl associated therewith and having an opening for registry with said stem bore, a serpentine band carried by said bowl adjacent said stem opening for rotation with respect to the same and means for effecting said rotation.

4. As an article of manufacture, a fitting for use with the bowl of a pipe comprising a serpentine band for cooperation with the inner wall of said bowl adjacent the stern opening of the same, scraper arms secured thereto and extending upwardly from the same in registry with said inner wall and an operating ring carried by said arms for effecting a rotation of the parts.

5. An attachment for the bowl of a pipe comprising a band for cooperation with the inner wall of said bowl adjacent the stem opening of the same, said band presenting a plurality of segments each formed with different sized openings, and means associated with saidband for selectively presenting said segments in registry with the stem opening of said bowl.
